Ba za a iya yi amsa tsari a lokacin da yana da ruwan da kuma yaɗuwar ruwa ta shirya 75%.

Yawan jiki a lokacin da ake amsa tsari ba zai iya zama ɗaya 0°C, kuma yawan jiki na tsari ba zai iya zama ɗaya ɗaya daga jiki na adabin yankin. Idan yawan jiki na tsari ya ƙara, ya kamata a sake karfi turbin har zuwa lokacin da yawan jiki na tsari ya zama ɗaya 10°C ɗaya daga jiki na adabin yankin, sannan za a iya yi amsa tsari.

1.2 Tsawon Wani Na Takaice Da Tsari

Tsawon wani na takaice da tsari ya kamata a ci gaba. Daga lokacin da ake rage mai ruwa zuwa lokacin da ake rage mai ruwa, tsawon wani na takaice da tsari ba zai iya zama:

• 16 sa'atu idan yaɗuwar ruwa ta shirya 65%.

• 12 sa'atu idan yaɗuwar ruwa ta shirya 75%.

2 Hanyoyin Amsa Tsari Na Kofin Turbin
2.1 Gaskiya Da Raba

Kabata da amsa tsari, ya kamata a duba hakkin abokan kasa da kuma ingantaccen aikinsu. Zabe da ɗaya daga gasar da kuma garurun vertikal ba zai iya zama 30°. Idan wannan ba zai iya zama ko idan abokan kasa suka haɗa da kofin turbin, ya kamata a yi amfani da girman kasa da kuma zabe don tabbatar da cewa ba zai iya samu tasiri sosai. Ya kamata a yi raba da mutum da ke fuskantar, kuma akwai mutane da ke raba duka cikin tanki don tabbatar da ba zai iya samu damu ko kusa da kofin turbin, windings, ko insulation components.

• Rage Mai Ruwa Ta Farko:Kabata da amsa tsari, rage wasu mai ruwa daga tanki don tabbatar da ba zai iya samu damu a lokacin da ake rage screws na top cover.

• Raba Da Gaskiya:Kasa top cover don tabbatar da yanayin da ke fitowa. Duba wurin no-load tap changer da kuma saki shekaru da ke fitowa. Kasa component da ke fitowa na no-load tap changer.

• Kasa Component:Kasa bushings, oil conservator, protective pipes, fan motors, radiators, tap changer operating mechanisms, oil purifier, thermometer, da kuma screws na top cover.

• Disconnection of Core Components:Kasa top cover na transformer, tabbatar da duk connections da ke bayyana tsari da top cover suka kasa kabata da amsa tsari.

• Amsa Tsari:Idan equipment da ke amsa ita ce mobile, za a iya amsa tsari zuwa wurin da ake fitowa. Idan equipment da ke amsa ita ce fixed, kasa tanki ba ga faduwa a lokacin da ake amsa tsari da kuma kasa tsari zuwa wurin da ake fitowa.

• Kasa Insulating Wrapping:Idan ana, kasa insulation wrapping na tsari (saki shekaru da ke fitowa don reassembly).

• Safi Da Raba:Amfani da rufin da suka sofu don safi windings, core supports, da kuma insulation barriers, tabbatar da ba a nan iron filings da suka haɗa da tsari.

3 Muhimmancin Da Za A Iya Yi A Lokacin Amsa Tsari Na Kofin Turbin
3.1 Raba Tsari

• Raba tightening bolts da nuts a silicon steel sheets da kuma structural steel da ke fitowa tsari. Tabbatar da duk nuts suka fito.

• Raba effectiveness of the core's single - point grounding connection copper strip.

• Don kofin turbin masu yawa, raba longitudinal cooling channels a tsari columns da kuma kasa duk blockages.

3.2 Raba Windings

• Raba axial compression of the windings.

• Tabbatar da inter-layer spacers suka fito, ba zai iya haɗa, ba zai iya haɗa, ko kuma ba zai iya haɗa.

• Tabbatar da high and low-voltage windings suka fito, ba zai iya haɗa, ba zai iya haɗa, da kuma insulation layers suka fito, ba zai iya haɗa, ba zai iya haɗa, ko kuma ba zai iya haɗa.

3.3 Raba Insulation Na Tsari

• Raba physical integrity of core insulation, including paper insulation on winding surfaces and lead insulation wrapping.

• Safi surface of core insulation da oil sludge and dirt, idan ana.

• Raba inter-phase and inter-coil insulation barriers.

• Don kofin turbin masu yawa, test for insulation aging. Signs include cracks under finger pressure, hardened and brittle texture, and darker color. Severe aging may cause insulation to shatter and become carbonized under pressure, indicating the need for replacement.

4. Raba Leads Da Support Structure

• Tabbatar da insulation distance of leads meets requirements.

• Raba tightness of clamping parts to maintain lead insulation distance.

• Raba insulation on lead surfaces and ensure that soldering and connections are secure without any broken strands.

5. Raba No-Load Tap Changer

• Raba contact pressure between moving and stationary contacts, which should be 25–50 N.

• Tabbatar da good contact at all switching positions, particularly the position in use.

• Raba overheating signs at contact points, and verify the tap changer's overall stability and the flexibility of the mechanical operating device.

6. Safi Da Raba Oil Tank

• Tabbatar da bottom of the oil tank is clean and free from sludge or debris, with no internal corrosion.

• After core inspection, flush the tank with qualified transformer oil, then open the tank drain to remove residual oil. Immediately reinstall the core and refill the tank with oil to the normal level.
